I think it's important to maintain proper layers and ensure that dll dependencies always go in one direction. Of course this is not always possible thanks to Microsoft design (or lack of it); but in the cases where we need to hack something I want it to be very explicit that something unusual is going on. If we make it so that any dll can easily import any other one, we'll quickly end up with an inextricable mess of cross-dll dependencies, simply because adding an import in the spec file for any dll that you may need is so much easier than having to use GetProcAddress and think about minimizing inter-dll calls because they are a pain to do. So there aren't really technical reasons we cannot do it, the issue is enforcing a structure by not making it too easy to do things the wrong way. -- Alexandre Julliard julliard(a)winehq.com

No, and I don't think it's a desirable feature, it's too error-prone. Besides, circular dependencies are really something to avoid, so it must not be too easy to do... (what does rpcrt4 need from ole32 BTW?) -- Alexandre Julliard julliard(a)winehq.com

BUG: mouse_event does not move pointer for relative coordinates
by Andriy P Oct. 12, 2001

Oct. 12, 2001

The attached test program moves pointer under Windows NT. Under Wine the pointer changes position on move request in absolute coordinates and does not move for relative coordinates. I found out that variables PosX and PosY ARE updated in queue_mouse_event in windows/input.c. Can somebody give me a hint where to go from there? I don't see further any difference in processing between absolute and relative movement. In case somebody will fix this bug, don't worry about different relative distance reported under Windows and in Wine. I alredy fixed that part and will submit the patch soon.

well, I must have this somewhere in my tree, but didn't publish it because Alexandre was somehow reluctant to use this type of features (not the reading of missing symbols from .spec files, but the circular deps). Alexandre, any "new" comments ? A+ > Well, can this be done with delayed imports yet?

winebuild and circular DLL dependencies
by Ove Kaaven Oct. 12, 2001

Oct. 12, 2001

Well, can this be done with delayed imports yet? I have a situation here where ole32 imports stuff from rpcrt4 (windows uses delayed imports for that), and rpcrt4 imports stuff from ole32 (again, windows uses delayed imports). It would be nice if I could use the winebuild delayed import mechanism to achieve this, instead of doing it manually with callout tables and stuff... but I suppose winebuild has to be changed to read the .spec files instead of using nm on compiled libraries... anyone working on it?

Re: Nasty Evil Memory Fragmentation fix

Well, we do have (almost) best fit, that's the only reason for having multiple free lists. It's just that we probably need more bins sizes to make it really useful. > We just need > to make sure Wine's free block selection routine uses the same strategies > as this allocator, and we'd get exactly the same performance as that > allocator, but without replacing the whole thing and sacrificing the > compatibility we have or introducing new bugs. Well, this depends how easy it is to plug the new allocator in; but if it doesn't require too many changes, it will certainly introduce less bugs than trying to tweak the existing code. Plus all the profiling work has been done already, which would have to be done on the Wine code. -- Alexandre Julliard julliard(a)winehq.com

Hi, I am running a compiler with wine. There are many fixme message that I can't switch off. What do they mean, is someone working on it, is the problem serious ? Not having them at stdout would be great :-) as the compiler output + wine fixmes get a little confusing...

The code is using the Win95 values now, but there is no reason we couldn't add a few larger values in the HEAP_freeListSizes array, instead of creating a new mechanism. > Despite the workaround, we're still not too pleased with the current > heap allocator.

A new allocator would definitely be a good thing. This one was done the way it is in order to use a compatible memory layout, but it turns out this is not necessary so we could scrap it. -- Alexandre Julliard julliard(a)winehq.com

SHGetSpecialFolderPathA and CSIDL_FOLDER_MASK
by Chris Green Oct. 11, 2001

Oct. 11, 2001

I've been looking at this function, and I am starting to suspect we have the wrong definition of CSIDL_FOLDER_MASK (currently 0x00ff). What I've been seeing (eg. installing MS Office 97) seems to imply that only the lower 6 bits, rather than 8, are related to the folder, and the others are something else. Does anyone else think that the mask should be 0x003f? regards Chris _________________________________________________________ Do You Yahoo!?
